Lock for collapsible cots



Sept; 15, 1931. w. SECUNDA LOCK FOR COLLAPSIBLE COTS Filed May 8. 1930ATTORN EY WITNESSES Patented Sept. 15, 1931 UNITED STATES PATENT QFFICEWILLIAM sEc'UNnA, orpnooxmm, ivnw YORK LOCK FOR COLLAPSI BLE COTSApplication filed May 8, 1930. Serial No. 450,794.

The invention comprehends a lock for collapsible cots which is cheap tomanufacture and which has body members pivoted to brackets, novel,strong and durable means being provided to lock the body membersrelatively to the brackets.

The invention further comprehends a lock of the class described in whicha leg of a collapsible cot has a bracket member with a flange, to whichbody members are pivoted, the body members also having flanges forengaging the flange on the bracket member for locking purposes.

The invention further comprehends a lock of the class described in whicha leg of the cot has a bracket member secured to its side with a flangeextending therefrom and a second bracket member secured to the otherside of the leg, a body member being disposed between the bracketmembers and pivoted thereto, and being provided with a flange whichengages the first mentioned flange when the body member is in normalposition for locking purposes.

Another object of the invention is to pivot the body member to a bracketmember, the body member being positioned to engage the leg when theflange on the body member engages the flange on the bracket member, forlocking purposes.

Another object of the invention is to provide a lock for collapsiblecots having a body member disposed between two bracket members which aresecured to opposite sides 5 of a leg, the width of the leg at thebrackets being reduced substantially to the width of the body member tohold the body member snugly bet-ween the bracket members, there being aflange on the body member engaging a flange on one of the bracketmembers when the parts are in normal position and the body member islocked against the leg.

Additional objects of the invention will appear in the followingspecification in which the preferred form of the invention is described.

In the drawings similar reference characters refer to similar parts inall the views,

A of which Figure 1 is a side elevation of a fragment of a cotto whichmyinvention is applied, b

Figure 2 is a transverse section on the line 2-2 of Figure 1,

Figure 3 is an enlarged plan view illustrating my invention with thebody members in normal position relatively to the bracket member, and IFigure 4 is a sideelevation, a part being broken away to illustrate theconstruction.

By referring to the drawings it will be seen that the cot is providedwith body members 10 which ma be supported at their outer ends in anydesired manner, the body members 10 at their inner ends 11 being pivotedto an outer bracket member 12 and to an inner bracket member 18.

These bracket members 12 and 13 are spaced apart and the inner bracketmember 13 is secured to the inner side 14 of the top of the leg 15 andthe outer bracket member 12 is secured to the outer side 16 of the topof the leg 15, this being clearly shown in Figures 3 and 4 of thedrawings. These bracket members 12 and 13 are preferably riveted to theleg 15, but it will be understood that they may be secured to the leg 15in any desired manner, the top of the leg 15 serving to hold the bracketmembers 12 and 13 spaced apart. body members 10 are disposed between thebracket members 12 and. 13, one at each side of the leg15, and the saidinner ends 11 of the body members 10 are secured to the bracket members12 and 13 by pivots 17.

The sides 14 and 16 of the upper end of the leg 15 are disposed closetogether so that the width of the leg between its sides 14 and 16 willbe substantially the same width as the body members 10. This will serveto prevent any lateral movement of the inner ends 11 of the body members10.

The inner bracket members 13 have inwardly disposed flanges 18 and theseflanges 18 are engaged by inwardly disposed flanges 19 on the bodymembers 10. It'will, there fore, be seen that when the body members 10are disposed horizontally and substantially at right angles to the leg15, the flanges 19 on the body members 10 will engage the The ends 11 ofthe flanges 18 on the inner bracket members 13. It will also be seen byreferring to Figure 4 of the drawings that when the body members 10 arein horizontal positions, at their in- .ner ends they will engage the leg15 so that ment of the flanges 19 with the flanges 18' on the innerbracket member 13, but also by the engagement of their inner ends 11with the leg 15. 1

Preferably there are two of these legs 15, as illustrated in Figure 2 ofthe drawings an these legs 15 are connected by braces 20 which willprevent the lateral movement of the legs 15 relatively to each other.

As has been stated, the outer ends of the body members 10 may besupported by any desired means. The flanges 18 on the inner bracketmembers 13 are preferably provided with apertures 21 to which memberssuch as springs 22 may be secured for supporting a canvas or othermember 23.

By referring to Figure 1 of the drawings it will be seen that the member23 is secured by the springs 22 or other suitable means to the flanges19 on the body members 10.

What is claimed is:

In a collapsible cot, a side rail comprising two aligned andspaced-apart body members, each composed of angle iron with thehorizontal flange directed inwardly of the cot, the horizontal flangesof both members cut away near their adjacent ends to form edge abutmentsperpendicular to the length of the body members and the vertical flangesof both members directed down- Wardly, an outer bracket overlying the adjacent ends of the vertical flanges on the outer side of the bodymembers consisting of a flat plate having its upper edge flush with theupper surface of the horizontal flanges of the body members, a verticalleg rigidly connected to the inner face of said bracket, the upperconnected portion of the leg being flat and equal in thickness to thevertical flanges of the body portions and being abutted on each vericaledge by an end of one of the said vertical flanges, the upper extremityof the leg being flush with the upper edge of said bracket, an innerbracket member lying opposite the outer bracket member and composed of ashort length of angle iron with its vertical flange directed downwardlyand overlying the inner face of the vertical flanges of the body membersand with its horizontal flange in the same plane as the horizontalflanges of the body member and having its ends abutting the saidabutment edges of the horizontal flanges, pivot members, one on eachside' of the leg, each pivot member passing ly locked against an edge ofthe flattened part of the leg and the abutments of the horizontalflanges resiliently locked against the horizontal flange of the innerbracket member.
